The rates in the NFL compared to regular society for all manner of crime is way higher.
I don't dispute that it's higher. Many of the players come from violent backgrounds, only to join a profession that not only encourages violence, but rewards it. Combine that with the sense of entitlement that's instilled in them at an early age, simply because they're good at playing a game.
But you're opening post seemed to be asserting that only in the NFL, or America, for that matter, is someone allowed to continue having a career once they've committed a despicable act. Sorry, but I call bs on that.
